    Default Vectra VXR Lambda Sensor Extension/O2 Spacer

    Does anyone know where I can purchase a Vectra VXR Exhaust Lambda Sensor Extension/O2 Spacer.

    I can find plenty for other models but not the Vectra VXR

    I'm getting an engine manage light and the code points towards a faulty Cat, which is probably the case given my car has done 122k, but I can't afford another cat at the moment so my mechanic says to knock it through and fit an O2 spacer.

    A custom made sports cat is often a cheaper alternative to a dealer bought cat.

    I think my o2 spacers were off ebay but they were purchased a long time ago mind you.

    tell your mechanic to keep a few bits from the cat,file 1 down and put it into the spacer before you screw in the lambda sensor.
    I had to do that to stop me getting eml on after gutting my precat,I had just the spacer first,but after a few hard runs still got code relating to decat.after putting the cat material in ,there was now more eml.done it to a few cars now.iv since had mine mapped out,but ran it the previous way for over 10k with no codes or problems.
